Panjnad River is formed by successive confluence or merger of the five rivers of the Punjab, namely Jhelum, Chenab, Ravi, Beas and Sutlej.

The correct answer is option 'C', i.e., Ganga.

Panjnad River is a river in Punjab, Pakistan, formed by the confluence of five rivers. These rivers are:

1. The Ravi River: The Ravi River is one of the five rivers that form the Panjnad River. It originates in the Himalayas in Himachal Pradesh, India, and flows through the Indian states of Himachal Pradesh and Punjab, before entering Pakistan. The Ravi River is an important tributary of the Indus River.

2. The Jhelum River: The Jhelum River is another tributary of the Indus River and is also one of the five rivers that form the Panjnad River. It originates in the Kashmir Valley and flows through the Indian-administered territory of Jammu and Kashmir, as well as Pakistan-administered Azad Kashmir and Punjab province. The Jhelum River is known for its scenic beauty and is an important source of hydroelectric power in the region.

3. The Chenab River: The Chenab River is the third river that forms the Panjnad River. It is the largest tributary of the Indus River and has its source in the Himalayas in Himachal Pradesh, India. It flows through the Indian states of Himachal Pradesh and Jammu and Kashmir, as well as the Pakistani provinces of Punjab and Khyber Pakhtunkhwa. The Chenab River is known for its swift currents and is an important river for irrigation and power generation.

4. The Beas River: The Beas River is another tributary of the Indus River and is one of the five rivers that form the Panjnad River. It originates in the Himalayas in Himachal Pradesh, India, and flows through the Indian states of Himachal Pradesh and Punjab. The Beas River is known for its scenic beauty and is an important river for agriculture and hydroelectric power generation.

5. The Sutlej River: The Sutlej River is the fifth and final river that forms the Panjnad River. It originates in Tibet and flows through the Indian states of Himachal Pradesh and Punjab, as well as the Pakistani province of Punjab. The Sutlej River is an important source of water and power in the region.

Therefore, the Ganga River is not included in the Panjnad River. The Ganga River is a major river in the Indian subcontinent and does not flow through Punjab, Pakistan. It has its source in the Gangotri Glacier in Uttarakhand, India, and flows through several Indian states, including Uttar Pradesh, Bihar, and West Bengal, before draining into the Bay of Bengal. The Ganga River is known for its cultural and religious significance and is considered sacred by Hindus.
